Systems and methods for creating personalized vision therapy sessions

Abstract

A user's visual disorders can be treated via a virtual reality (VR) system, which can include a VR headset in electronic communication with a computing device. The computing device causes vision tests to be displayed on the VR headset. Using varying combinations of eye-tracking sensors, eye-tracking cameras, motion-tracking sensors, handheld devices, and microphones, the VR headset can collect data about the user as she completes the vision tests. Using the data collected by the VR headset, the computing device can evaluate the user for various visual disorders and develop a personalized vision therapy plan for the user. Optionally, advanced algorithms in the computing device dynamically alter the vision therapy plan based on the user's performance and the progression of her visual disorders.

What is claimed is: 
     
         1 . A method for adapting personalized vision therapy sessions, the method comprising:
 at a first session:
 administering a series of visual tasks on a screen of a virtual reality (VR) headset worn by a user, wherein the series of visual tasks comprises a quantity of visual tasks, an order of visual tasks, a nature of at least one visual task, and a difficulty of the at least one visual task; 
 monitoring a user's eye movements while the user completes the series of visual tasks; 
 processing the user's eye movements to analyze a user's vision progress; and 
 adjusting the series of visual tasks based on the user's vision progress; and 
   at a second session, administering the adjusted series of visual tasks.   
     
     
         2 . The method of  claim 1 , wherein administering the series of visual tasks comprises displaying moving objects in a virtual environment and prompting the user to track the moving objects. 
     
     
         3 . The method of  claim 1 , wherein administering the series of visual tasks comprises displaying objects at varying distances from the user and prompting the user to target the objects. 
     
     
         4 . The method of  claim 1 , wherein monitoring the user's eye movements comprises monitoring a user's gaze direction. 
     
     
         5 . The method of  claim 1 , wherein monitoring the user's eye movements comprises monitoring a user's fixation stability. 
     
     
         6 . The method of  claim 1 , wherein monitoring the user's eye movements comprises monitoring a user's response accuracy. 
     
     
         7 . The method of  claim 1 , wherein monitoring the user's eye movements comprises monitoring a user's response times. 
     
     
         8 . The method of  claim 1 , wherein processing the user's eye movements comprises processing the user's eye movements in real-time as the user completes the series of visual tasks. 
     
     
         9 . The method of  claim 1 , wherein adjusting the series of visual tasks comprises changing the quantity of visual tasks. 
     
     
         10 . The method of  claim 1 , wherein adjusting the series of visual tasks comprises changing the order of visual tasks. 
     
     
         11 . The method of  claim 1 , wherein adjusting the series of visual tasks comprises changing the nature of the at least one visual task. 
     
     
         12 . The method of  claim 1 , wherein adjusting the series of visual tasks comprises changing the difficulty of the at least one visual task. 
     
     
         13 . The method of  claim 12 , wherein changing the difficulty of the at least one visual task comprises changing a speed of a moving object when the at least one visual task comprises tracking the moving object. 
     
     
         14 . The method of  claim 12 , wherein changing the difficulty of the at least one visual task comprises changing a size of an object when the at least one visual task comprises targeting the object. 
     
     
         15 . The method of  claim 12 , wherein changing the difficulty of the at least one visual task comprises changing a duration of the at least one visual task. 
     
     
         16 . The method of  claim 1 , wherein adjusting the series of visual tasks comprises changing at least two of the quantity of visual tasks, the order of visual tasks, the nature of the at least one visual task, and the difficulty of the at least one visual task. 
     
     
         17 . The method of  claim 1 , further comprising changing the difficulty of the at least one visual task in real-time as the user completes the series of visual tasks. 
     
     
         18 . A method for developing a personalized vision therapy session, the method comprising:
 administering an assessment on a screen of a virtual reality (VR) headset worn by a user, wherein the assessment comprises a series of vision tests configured to identify visual deficiencies;   monitoring a user's eye movements while the user completes the assessment;   processing the user's eye movements to identify a type and a severity of a user's visual deficiencies;   accessing a library of visual tasks; and   based on the type and the severity of the user's visual deficiencies, determining a quantity, an order, a nature, and a difficulty of the visual tasks from the library that constitute the personalized vision therapy session.   
     
     
         19 . A system for creating a vision therapy plan, the system comprising:
 a virtual reality (VR) headset worn by a user, the VR headset comprising a screen, one or more eye-tracking sensors, and one or more eye-tracking cameras; and   a computing device in electronic communication with the VR headset, the computing device being configured to administer an assessment on the screen of the VR headset and develop a vision therapy plan for the user by processing a user's responses to the assessment and accessing a library of visual tasks,   wherein the one or more eye-tracking sensors and cameras are configured to collect the user's responses to the assessment.   
     
     
         20 . The system of  claim 19 , wherein the computing device is further configured to assess a long-term effectiveness of the personalized vision therapy plan and generate recommendations for adjustments to the vision therapy plan.
